Product Description

Product Description

Introducing the (H)GWBEB type outdoor high-voltage isolation switch, a vital component designed to excel on 10/12/15/24kV high voltage power transmission and distribution lines. Engineered as an isolation disconnect switch, it enables the seamless opening and closing of single-phase or three-phase circuits while maintaining voltage presence but without load, ensuring safety and efficiency in power management.

Crafted for single-phase integration within three-phase line systems, this switch stands out for its straightforward architecture, economic viability, and user-friendly operation. Offering rated current options of 200, 400, 600, 800, 1000, and 1250 amps, it comprises a robust assembly of a base, post insulators, conductive components, and a mechanical section. The innovative gate knife structure ensures precise circuit management, with each phase featuring dual conductive blades and external compression springs. By adjusting the spring height, optimal contact pressure for the gate knife is achieved. The switch is maneuvered using an insulated hook stick and includes a convenient self-locking feature for assured operation.

Working Environment:

This switch operates effectively at altitudes up to 1000 meters;

The ambient temperature range is designed for extremes, with a maximum of +40°C and a minimum of -30°C;

Engineered to withstand outdoor wind speeds up to 35 meters per second;

Built to endure seismic intensity up to 8 degrees; the installation site must be stable, avoiding frequent severe vibrations.

The installation area must be free from gases, chemical deposits, salt mist, dust, dirt, or any explosive or corrosive substances, which could severely impact the switch’s insulation and conductive reliability.

Note:

WHEN THE ABOVE NORMAL USE CONDITIONS ARE EXCEEDED, THE USER CAN NEGOTIATE WITH THE COMPANY.

Installation, Use and Adjustment

Pre-installation work

1. Thoroughly clean all components to remove dust and dirt, paying particular attention to the insulating porcelain bottle’s surface.
2. Ensure the wiring surface of the ground screw is scrubbed clean for optimal connectivity.
3. Apply a protective layer of industrial Vaseline to the rotating parts and contact areas to ensure smooth operation.
4. Inspect the contact surface and adjust the compression spring height to ensure the contact pressure meets the specifications outlined in Table II.
5. This switch is exclusively designed for hoisting applications, intended for use alongside transformers on the line.
6. The switch’s rated current spans 200-400 amps, typically utilizing three mounting holes. For 600-1000A, three mounting holes are standard.

Annual inspections are essential for maintaining optimal performance of the switch. Regularly check the following components:
Ensure all conductive parts, contact surfaces, and insulating porcelain bottle surfaces are free from dirt.

Inspect all components for damage, giving special attention to the insulating porcelain bottle for any signs of damage or cracks.

Verify that the contact surfaces of all conductive parts remain in good condition.
